Answer:
A rock is a naturally formed, non-living Earth material. Rocks are made of minerals. ... A rock may be made of only one type of mineral. More often rocks are made of a mixture of different minerals.
Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Metamorphism also happens when rocks are buried deeply during the process of mountain building. The kind of metamorphic rock made depends on the kind of original rock; for example, sandstone is turned to quartzite, shale is turned to slate, and limestone is turned to marble.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Nitrogen bases pair with bases that are...

complementary and identical
identical
Nitrogenous bases basically pairs with bases that are complementary. The correct option is B.
What are nitrogenous bases?Nucleobases, also referred to as nitrogenous bases or purely bases, are nitrogen-containing biological molecules that form nucleosides, which are then constituents of nucleotides, all of which are the basic building boxes of nucleic acids.
A set of 5 nitrogenous bases is used to build nucleotides, which then in results nucleic acids such as DNA and RNA.
These bases are critical because their sequencing in DNA and RNA is how information is stored.
A base pair in DNA are complementary to each other. Under normal conditions, the nitrogen-containing bases adenine (A) and thymine (T) pair, whilst also cytosine (C) and guanine (G) pair.
The structure of DNA is formed by the binding of these base pairs.
Thus, the correct option is B.

Which of the following is not an example of mutualism?
Plsss help
Answer:
D. Conifers and Grasses spreading their pollen with the wind.
Explanation:
Let's start with what mutualism is. Mutualism is when both parties of a relationship benefits. So, when you go to the doctor, this would be mutualism. The doctor is getting paid, and you are getting healthy. Both sides benefit!
Now let's go thrugh out examples.
Moths drinking nectar and pollinating night blossoming flowers: The moths get fed (nectar), and the plants get pollinated (their whole purpose). Both sides benefit.
Bees drinking nectar and pollinating many angiosperms of food supply: This option might seem confusing because of the term angiosperm. I promise it isn't! Ignore angiosperm. Bees are drinking nectar -> they benefit. The other thing is getting pollinated. All plants like getting pollinated, no matter their fancy name. So both sides benefit!
Beekeepers maintaining colonies of bees and moving them to different farms and orchards: This one might also have been hard, because it requires sme critical thinking. Let's look at the beekeepers first. Beekeepers make money off of honey when they have bees, so they benefit. But do bees benefit in this relationship? Yes! Bees like having lots of plants to pick from to get their pollen. By being moved to an area with lots of plants, they get more pollen, so they benefit!
Now, we know the last one HAS to be right. But let's go through it anyways.
Conifers and Grasses spreading their pollen with the wind: Right away we know the conifers and grasses are benefitting. They want to spread their pollen- why else would they do it? But, to be mutualism, another party has to be benefitting. In this equation, there is no other party. Maybe you thought the win, or maybe you thought of the fields. What are they getting out of this relationship? Nothing. This is not mutualism.
Hope this helps and feel free to ask for any more clarification!

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.
Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
What are Autotrophs?
Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.
The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.
Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.
Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.
Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

The level of organization in the human body initiates with the cell and process in the manner which is as follows:
Cell < Tissue < Organ < Organ system < Organism. What is the level of organization?The level of organization may be defined as the process of sequence from the structures that are simplest in nature. It is usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.
In organisms, a cell is the fundamental structural and functional unit of life. The collection of cells constitutes the formation of tissue which makes an organ that plays a specific function. Groups of organs form organ systems. While all cells, tissues, organs, and organ systems combine in order to form multicellular organisms.
